ASNQ is based on the NQ dataset, which is a corpus designed to (i) study MR tasks, and (ii)
solve several problems of previous corpora such as SQuAD [1]}.
MR models, e.g., [2]}, are different from those used for AS2 and beyond the purpose of our paper. It is still worthwhile to mention that [3]} (2017) explored transfer learning for the BiDAF model for MR.
